Jinko Solar is the world leader in solar panels. The N-type negative mono cell, in contrast to the P-type, is doped in Phosphorus. This treatment ensures slower aging of the cell. These panels, therefore, have a much lower degradation than the current P-type panels. With a degradation of only 0.4% per year, Jinko Solar offers you an exceptional power guarantee of 87.4% over 30 years with this panel! The yield of this 375 Wp N-type solar panel is therefore comparable over the life of the panel to the yield of a standard P-type solar panel of 390 Wp. The Half Cell technology ensures less resistance, resulting in higher efficiency. Also, with shadow on the lower half, the upper half will continue to function fully. Jinko Solar guarantees based on very strict tests for the PID resistance of the panels. Jinko Solar offers a 25-year manufacturer’s warranty on this solar panel.
